  1. Latest Update: As of now the drive RSVP signup is still full. However as i have noticed that @Archibald Jurdi was not able yet to signup for one single drive on the weekend, i will add him to the drive to get him to have at least one Carnity drive. Please confirm if you can make it Archibald, otherwise the spot will be given to @Ahab Shamaa
  2. We can distinguish 3 different controls on most modern 4x4 cars: 1) ABS (Anti-Lock braking system) A standard Anti-lock Braking System uses four wheel speed sensors, a hydraulic pump, hydraulic valves, and a controller. The controller in the ABS system monitors the speed of each wheel using the wheel speed sensors, which are usually hall effect sensors. If the controller sees that one wheel is decelerating at a rate that couldn't possibly correspond to the vehicle's rate of deceleration, it actuates the hydraulic valve in that wheel's brake line to reduce the brake pressure applied to that wheel. This allows the wheel to turn faster. Once the wheel is back up to speed, it uses the pump to introduce the pressure back into that brake line, applying that brake again. When the controller sees rapid deceleration again, it activates the valve and the cycle repeats about 15 times per second. The ABS system is mainly made to avoid your brakes from locking up during hard braking, which would cause your vehicle to start slipping. 2) ESC (Electronic Stability Control) Electronic stability control (ESC) is a computerized control system that applies brakes to individual wheels and reduces engine power to ensure that drivers maintain control of their vehicles. The six main components of an ESC system are: wheel speed sensors, a control module, a steering angle sensor, a yaw rate sensor, an accelerometer, and the hydraulic modulator. Note that the hydraulic modulator is the same one used in an ABS system, meaning that ESC adds only the yaw sensor, an accelerometer, and steering angle sensor to a standard ABS system. To understand how this system works, imagine you are driving down the highway at 60 miles per hour. You swerve left to avoid hitting a raccoon. What happens in the short duration to follow? The yaw rate sensor determines where your car is pointing, the steering angle sensor determines where your front wheels are pointing, the accelerometer determines if your vehicle is sliding, and the wheel speed sensors monitor each wheel’s speed. If you turn your wheel very abruptly to the left, your vehicle will initially under steer. This is simply Newton’s First Law. Since the front tires do not yet have enough traction, they slide and the car continues to move forward. The control module recognizes the discrepancy between the intended path (communicated by the steering angle sensor) and the actual path (communicated via the yaw rate sensor) and sends a signal to the hydraulic unit, directing it to increase braking power to the left rear wheel. This causes the automobile to rotate left (the desired response). If necessary, the control module will also reduce engine power by sending a signal to the throttle actuator asking it to close the butterfly valve. 3) Traction Control Traction control works in a similar way as ESC. If a vehicle is unable to gain traction in icy conditions, one wheel will spin while the other simply remains stationary. This is the nature of an open differential: the wheel with the least traction receives the most power. This is undesirable in low-traction situations. As such, traction control can step in. Traction control monitors wheel speed using ABS wheel speed sensors. If a wheel is slipping, traction control reduces engine power to help the wheel regain traction. If necessary, traction control can also apply the brakes to the slipping wheel. This will transfer power to the other wheel (which now has more "traction") depending on surface conditions. As you can see above, these electronic aids are functioning together, all with the same aim of increasing safety for you and your passengers. During dynmamic offroading in sand, the speed and yaw sensors will assume that you are losing traction, and the system will start to react with reducing engine power and diverting power to the wheels that still have traction. That is the main reason we disable these systems.

  4. and when you go to sleep don't forget to turn off the light 😆
  5. Carnity Whatsapp Drive Notification This Whatsapp group is only to send out notifications on the upcoming drives (no chat). Thanks for informing @Veedooshee. @Melenany i have added you to the drive. Kindly confirm if you can make it.
  6. I have two of these sideshooters on my front bumpers and they really help a lot when aimed at the corners. Dragon Mart has them from Toby's brand.
  7. Hi @Christian Andras your points and concerns are completely valid. I used to have a double led bar mounted on the roof, but the wind noise was quite horrible and the reflection on the hood was also there but by pointing them a little bit upwards i was able to minimize that. From my opinion i have seen better results from a slightly smaller bar with latest LED technology mounted on the front grille.
  8. Well deserved @SureshVNair ! See you soon with that fantastic Rubicon !
  9. Congrats @Athula Dharmadada so happy to see you growing with us, as you have left the Pathfinder days behind See you soon in the sand !

  14. DRIVE REPORT A beautiful active morning 😆 An Absolute Newbie drive always comes with its surprises, but is all worth it because of the smiles of the new members at the end of the drive. This morning was a bit eventful and these things happen sometimes. The desert comes with its own surprises. The first surprise was when @Javid Ahamed his Ford Explorer had a first hiccup/stuck a few dunes inside. After looking for the 4x4 buttons we finally had to pull the car back out as we realized it was a 2-Wheel drive car. A little while later, @Antonio Rivera his beautiful black Wrangler starting smoking and going from the smell it could only be the clutch that got fried. We tried waiting a bit, and even tried to drive a little portion in low gear, but eventually the only option was to pull it out back to the road and get the recovery truck. @Federico Galbieri did fantastic as my second lead, listening perfectly to my instructions over the radio and re-routing where needed. Well done ! @Dr Tariq Mahmood with the White Prado was gliding effortlessly through the dunes. Very impressive ! @frederic demolder the Landrover Discovery Sport is a very capable offroader, but does not have a good approach angle and clearance For Newbie level drives you will be fine, You drove really well today and was not afraid of shoveling. Super attitude ! @Jonathan Maumy with the beautiful Black Montero Sport you did amazing too and will probably get addicted soon @Federico De Chirico that Fortuner was a beast that woke up as soon as we deflated it a bit more. Well driven buddy ! @Vinojps with the nice red Wrangler drove effortlessly today. Nice work !! @Rob Harper and @Jack Thomas two superdudes who both drove amazing ! @Sandi88 you have driven before in the desert and it shows, but please understand that safety is our prime focus and leaving the convoy and going for a play is not acceptable. @Vishnu Sasidharan the same applies, where Vanessa has clearly told you to stay within the convoy you again ignored her instructions. This is not OK guys. We need to make sure all our drivers who are under our wing are safe and are not getting themselves into trouble. Unfortunately the COVID regulations were also not followed by some drivers/passengers , as we requested to everyone to wear a mask in case you need to exit the car. Please do take note that is this occurs for the next drive we will ban members who keep thinking they are above the law. Only by following the government rules we will be able to continue these drives. Moving forward you all will be joining the Newbie drives and not an Absolute Newbie drive. Drives are announced every Sunday at 11 am, and they go live on Sunday at 7 pm. Due to the high demand, these drives get full in about 10 minutes, so please be online at 7 pm to book your spot. For the next drives, please bring along a deflator, pressure gauge, flag and radio as a minimum. Learn to deflate your tires and checking them precisely Learn to fix a flag on your car Learn to program and fully charge your radio Also like I mentioned during the debriefing, join the Carnity Whatsapp Drive Notification to get the latest updates on the drives, so that you can RSVP on time for the next weekend's drive. Please have a look at below topic which describes the tools needed for every level. There is a separate tutorial inside which explains which radio we recommend and how to program them: (Please do not buy the Baofeng 888S spare radio we gave you, as these cannot be programmed without a special cable and software). Please have a look at below grading structure that explains various off-road levels: See you guys soon in the sand again ! @Antonio Rivera i hope your car is ok and recovery was able to help you. I will send you a text to handover the radio one of these days, no worries.
  15. DRIVE RSVP IS NOW CLOSED Please find the convoy list for tomorrow above. @Vanessa8580 and i will be supporting you throughout the drive. Some remarks: - Please do watch the Absolute Newbie Briefing video completely, as this contains so much essential information that will make your first drive more pleasant as you will feel totally prepared. - Please abide by the COVID19 regulations we have put in place for everyone's safety. As soon as you step out of the car for inflation or deflation, always wear your mask. - If you do not have a radio yet, no worries for your first drive we will hand over a spare radio that you can use tomorrow. For the ones that have a radio, you can tune in on Carnity Channel 4: 446.08125 Mhz. See you guys tomorrow at 05:30AM Sharp ! PS For emergency cases my mobile number is 056 504 26 32
